this application Febru- 3 Claims. (01. 105-112) This invention relatesto an engine or motor foundation for vehicles andis a division of mypatent application, Serial No. 724,112 filed May 5, 1934.

The object of this invention is to combine the engine foundation of amotor vehicle with the fuel, oil and water tanks into one unit in orderto save valuable space and to make this space available for otherpurposes.

Another object of this invention is to construct the engine foundationin such a way that it also willserve as a portion of the floor structureas outer cover of the vehicle body thereby distributing the weight ofthe engine and service liquids uniformly over the frame structure.

A further object of this invention is to locate the various serviceliquids required for operating the power engine as close as possible tothe engine to save on length of the necessary piping and to keep thecenter of gravity of the vehicle as low as possible, in order to obtaina good riding quality.

This invention is described in the following specification and theattached drawing illustrating its adaptation to a car body.

Fig. 1 is a plan view of the invention.

Fig. 2 is a cross-sectional view along the line 22 in Fig. 1, showingthe engine foundation extending the full height of the floor structure.

Fig. 3 also is a cross-sectional view of this invention in amodification showing a separate bottom for the car structure. 4

Figs. 1 to 3 show an improved construction of an engine foundation of arailway car, preferably made of welded steel plates. This enginefoundation not only supports the main power unit of the car, but alsoserves as a fuel, oil and water and "tank, and bwidesas a floorstructure which'connects the main longitudinal supporting girders of thecar body. Such a combination makes the bottom of the car bodytremendously rigid and solves the storage of the service liquids in themost ideal way, since it will bring the center of gravity of the carvery low. A great advantage of this construction is the possibility ofintegrally connecting the power unit foundation with the structuralportion of the car body. Another advantage is that the pipe lines (notshown) leading from the storage tanks to the power unit will be veryshort and therefore simple anddirect.

The foundation member ll of the power unit If is divided by longitudinalpartitions l3 and transverse partitions I4 and llinto a number ofcompartments reserved for fuel, oil and water. The partition walls alsoserve as stiffeners. The

partitions u are provided with openings l6 and H to. unite two or morecompartments into a single one, depending on requirements. Thepartitions I5 are unperforated. The top l8 of the foundation plate.(Flg. 2) rests on the longitudinal supporting girders IQ of the carbody and also carries the floor 20. The bottom 2| of the foundationmember forms the bottom of the car body. An extension bracket 22 weldedto the bottom of the foundation member is secured by bolts 23 to aflange of the longitudinal supporting girders of the car body and thetop of the foundation member is fastened to the top of the supportinggirders by bolts 24 and 25. Hand-holes 30 and 3| are provided in thefoundation member to make the bolts accessible.

The power unit may be fastened to the foundation member either directlyor a resilient member 32 may be employed between the foundationmemberand power unit to reduce the transmitted to the car body.

Fig. 3 shows a modification of the arrangement vibration shown in Fig.2. The foundation member in this case is made of lower height. Insteadof securing the foundation member 35 rigidly to the car body,a'resilient mounting 36 is employed, whereas the power unit I! isfastened rigidly by bolts 3l to .the foundation member. In 'order togive the car body sufficient rigidity, transverse members 38 connect thelongitudinal supporting girdmaybe made within the spirit and scope ofthisinyention as'deflned by the appended claims. I claim:

1. In a railway car, a car body, including two longitudinal supportinggirders forming the lower edges of the car body, transverse membersconnecting said supporting girders, an engine foundation connectingmember above and resiliently supported on said transverse members andforming a container to be used for storing a service liquid; z

2. In a railway car, a car body, including two longitudinal supportinggirders forming the lower edges of'the car body, transverse membersconnecting laldgupporting girders. an enginefounlongitudinally extendingsupporting girders forming the outer lower edges of the car body, of astorage tank resiliently supported on and extending between saidgirders, and a motor mounted on and carried by said tank.
